It fits the A1710130, ATSC710, and TVS3970A models. Cell dimensions are 99.10 × 65.55 × 6.70mm — physically identical to the original PL903295 pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA1710130 \/ ATSC710 \/ TVS3970A compatibility:\u003c\/strong\u003e\n    All three models share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. One pack covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the DVB-T decoder and LCD display load simultaneously. The BMS held the protection threshold correctly and did not trigger a false over-current cutoff during tuner lock-on, which draws a brief current spike.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eChannel list after battery swap:\u003c\/strong\u003e\n    DVB-T receivers store channel data in volatile memory. Removing the battery fully wipes that data. Run a complete channel scan immediately after fitting this pack — do not skip it, even if the device powers on normally.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReception breaking up at low battery on DVB-T receivers\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DVB-T tuner in these units requires a stable voltage to maintain full RF sensitivity. As the battery sags below roughly 6.8V under load, the tuner's front-end amplifier loses gain. The picture pixelates or freezes before the low-battery indicator even activates. Replacing the battery pack restores the voltage headroom the tuner needs to decode weak signals cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice powers on but finds zero channels after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA discharged or marginal battery can allow the unit to boot but leave the tuner below its minimum operating voltage — typically the full 7.4V nominal rail. In this state the tuner initialises but cannot reach the sensitivity threshold required for a successful scan. Charge the new battery to full before running a scan. If the scan still returns zero channels, the antenna connection or regional frequency settings need checking.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360229425242,"sku":"BWCS-HAT71TB-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360229458010,"sku":"BWCS-HAT71TB-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360229490778,"sku":"BWCS-HAT71TB-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT71TB-1.webp?v=1778611023","url":"https:\/\/batteryweb.com\/products\/digital-prisim-a1710130-replacement-battery-74v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
